Calculate the energy change (q) of the surroundings (water) using the enthalpy equation

qwater = m x c x ?T.

We can assume that the specific heat capacity of water is 4.18 J / (g x ?C) and the density of water is 1.00 g/mL.

The water has absorbed the heat of the metal. So, qwater = qmetal

2.Using the formula qmetal = m x c x ?T, calculate the specific heat of the metal. Use the data from your experiment for the metal in your calculation.

Part II:

my graph consits of
Calorimetry Lab Part I
Measure mass of metal41.664 g
Distilled water measurements 25 mL
Distilled water temperature 25.3 Celsius
Temperature of metal 100.5 Celsius
Temperature of mixture 35.7 Celsius
and second graph

Calorimetry Lab Part II
Measure mass of metal25.605 g
Distilled water measurements23 mL
Distilled water temperature25.3 Celsius
Temperature of metal100.3 Celsius
Temperature of mixture29.1 Celsius

i dont understand this at all, i will like some help please and thank you.
